Death Star 33

Death Star 2-33

Here's how to get 3 stars on Death Star 33 in Angry Birds Star Wars:

Bird 1: Fire your Yellow Han Solo Bird at the bottom of the screen, towards the Storm Trooper Pig near the barrier in the back. Just before making contact, fire Han's blaster up, to the top of the barrier, breaking it.

Bird 2: Fire your Giant Chewbacca Bird into the middle of the floating objects. It should move them enough to push objects into the back planet's gravity, killing the rest of the pigs.
